Introduction

Congratulations on your purchase of Triplett AM200 Mini Thermo­Anemometer. This professional meter, with proper care, will provide
years of safe reliable service.

Meter Description

1. Vane impeller

2. Precision thermistor

3. LCD display

4. POWER and HOLD key

5. UNITS and MODE key

6. Battery compartment (on rear)

7. Swivel handle and storage case

8. Lanyard holder

9. Impeller set screw (on rear of meter)

4. OPERATION

Operation

Select the desired units for air velocity and temperature by
momentarily pressing the UNITS/MODE key from a powered down

condition. The LCD will show temperature units (oC or oF) and Air
Velocity units. Press the UNITS/MODE key repeatedly until the desired
units are displaying. When finished, press the ON/OFF/HOLD key
momentarily to restart the meter with the desired units.
Power the meter by pressing the ON/OFF/HOLD key momentarily.
The Dual Display will illuminate. The top (larger) display indicates
air speed and the lower display indicates temperature.
Position the meter so that the measured airflow enters the meter
vane from the rear of the meter (opposite side from the front panel
logo, part number, etc.).
Activate Data Hold (to freeze the most recent display), by pressing
and holding the ON/OFF/HOLD key while taking measurements. To
return to normal operation, release the key and restart the meter.
Max operation: After a measurement session, press and hold the
UNITS / MODE key until the MAX icon appears on the lower left-hand
side of the LCD. Both the Air Velocity and Temperature indication will
represent the highest readings measured since the meter was last
powered.
Average mode operation: Normally the meter averages readings
every 2 seconds. To select 5, 10 or 13 second averaging, first press
and hold the UNITS/MODE key until the MAX icon appears. Next,
press the key again momentarily and the AVG icon will appear. The
13 second average mode is selected. Now press the key again and
the number 5 will appear. Leave it there if an average of 5 seconds is
desired. Press the key once more for a 10 second average mode. To
return to normal operation press the UNITS/MODE key repeatedly
until all lower left-hand icons disappear.
Wind chill indicator: Press and hold the UNITS/MODE key until the
MAX icon appears. Press the key repeatedly until the WCI icon
appears. The temperature display will now factor in the wind chill. To
return to normal operation, press the UNITS/MODE key again and
the WCI icon will disappear.

AUTO POWER OFF: After approx. 20 mins, if meter keys are not

Maintenance

Battery Replacement

The AM200 has a low battery indicator (battery symbol). Important: Turn the meter off before
opening the battery compartment. Using a coin, turn the battery compartment cover CLOCKWISE
to remove it. Once opened, observe the position of the battery, placing the new one in the same
position. Secure the battery compartment cover and dispose of the lithium battery in accordance
with local, state, or national disposal codes.

Other Battery Safety Reminders

Impeller Replacement

All EU users are legally bound by the Battery Ordinance to return all used
batteries to community collection points or wherever batteries / accumulators

are sold.
Disposal in household trash or refuse is prohibited.
Disposal: Follow the valid legal stipulations in respect of the disposal of the device at
the end of its lifecycle

Never dispose of batteries in a fire. Batteries may explode or leak.
Never mix battery types. Always install new batteries of the same type.

Remove the set screw next to the impeller assembly (on the rear of the meter). Twist the impeller
assembly counter-clockwise to the OPEN position and remove

it.
Install impeller by inserting & twisting the new impeller assembly clockwise Tighten
the set screw.

CFM Measurements

Measure the area of the duct using the diagrams below for rectangular and circular ducts (If the
duct measurements are made in inches, divide the inches by 144 to get the area in square feet).
Plug the area value (in square feet) in the cubic equations below. Note that the air velocity must be
plugged into the cubic equations also.

CFM (ft3/min) = Air Velocity (ft/min) x Area (ft2)
CMM (m3/min) = Air Velocity (m/sec) x Area (m2) x 60
